Final answer:
Option (C), The wing structures of bats and birds are examples of homologous structures indicating a common evolutionary past, which is an example of divergent evolution, not convergent evolution.
Step-by-step explanation:
The wing structures of bats and birds are examples of homologous structures, indicating that they share a common evolutionary past. This commonality suggests that their wing structures are a result of divergent evolution from a common ancestor, rather than convergent evolution.
In contrast, when we look at insect wings compared to those of bats and birds, we are seeing an example of convergent evolution, where different species independently evolve similar traits. This occurs because the two types of organisms are adapting to similar environments or challenges, but do so separately from each other, as seen with the adaption of flight in bats and insects, with wings evolving from very different original structures.
